Distribution of the fraction of the line of sight within finite-infinity regions on the sky for different distance slices. The first five of the six panels show the full sample for different slices in co-moving distance, while the last panel shows the selected sample for its entire distance range. The area covered by the (overlapping and partially transparent) circles in the individual depends on the richness of the group to which the fraction of the line of sight within finite-infinity regions was calculated. The colour coding provides the value of the fraction of the line of sight within finite-infinity regions for the individual targets.
